Deep Groove Ball Bearings FAG 6209 -TB-P63

The FAG 6209 -TB-P6-C3 deep groove ball bearing combines enhanced P6 precision, C3 clearance and a hard-fibre cage, with dimensions of 45 x 85 x 19 mm.

The 6209 -TB-P6-C3 deep-groove ball bearing is a single-row rolling bearing with a 45 mm bore, an 85 mm outer diameter and a width of 19 mm. Manufactured from standard roller bearing steel 100Cr6, this open design primarily accommodates radial loads. As it does not feature integrated seals, the bearing is suitable for designs in which lubrication is supplied via the housing system. This version is characterised by tight manufacturing tolerances and a specialised cage material.

What is the 6209 -TB-P6-C3 deep groove ball bearing suitable for?

This deep-groove ball bearing is typically used in industrial machinery and drives that require precise shaft guidance and thermal reserve. Due to its open design without a flange or groove on the outer ring, the bearing unit can be flexibly fitted into prepared housings. The 100Cr6 material covers an operating temperature range of –20 to +120 degrees Celsius. Designs with external oil or grease lubrication benefit from unobstructed access of the lubricant to the rolling elements and raceways.

What are the advantages of a hard-fibre cage, P6 tolerance and C3 clearance?

The combination of a hard-fibre cage (TB) and increased C3 radial clearance gives this rolling bearing special properties. The hard-fibre cage is characterised by its low weight and elastic behaviour, whilst the C3 radial clearance compensates for heat-induced expansion of the shaft during operation. The P6 tolerance class (corresponding to ABEC 3) also ensures tighter dimensional and running tolerances than with standard bearings. When designing the assembly, ensure that the bearing housing is effectively sealed against the ingress of contaminants.
